The area is underlain by pelitic and psammo-pelitic schists and gneisses of the Shuswap Metamorphic Complex, intruded by biotite orthogneiss and almandine muscovite alaskite. Foliations in the metasediments range from east to northeast (100 to 148 degrees) with dips between 35 and 60 degrees north and northwest. The rocks are folded by an early set with axes plunging north to northwest at 20 to 45 degrees.

Stratiform copper-lead-zinc-silver mineralization occurs in a well defined zone up to several metres thick and traceable over 1.0 kilometre with a possible strike length exceeding 1.9 kilo- metres. The zone includes mineralized pyrrhotite biotite schists, massive pyrrhotite sulphide, and pyrrhotite garnet actinolite gneiss with associated chalcopyrite, galena and sphalerite. Modal economic sulphide minerals may be present up to 2 per cent.
